Our first shop on the busy North side of Main Street, the Antonio Diamond Boutique started life as a tiny bazaar in the ‘50s and ‘60s, evolving into a porcelain and crystal retailer in the 70’s, 80’s and 90’s and finally, following a dramatic enlargement of the premises in 2001, into Gibraltar’s finest jeweller and watchmaker.


Our brand portfolio is impressive and we are trusted retail partners with Breitling, Tag Heuer, Montblanc, Messika, Oris, Longines and a host of other quality watch and jewellery brands. We are also major stockists of very high-end GIA loose diamonds, all at tax-free and duty-free prices.


The Antonio Diamond Boutique is run by Raja Menghnani since 2001. Raja is a household name in Gibraltar, a walking encyclopedia of luxury retail, with nearly two decades of experience servicing luxury customers from all over the world.  As a GIA Accredited Jewellery Professional, he is also highly knowledgeable in the field of precious and semi-precious stones.
